Ok ladies, what’s the most important attribute of your best clients (in other words – what makes some guys more likely to have a better time than others)?

Is it confidence, physical appearance, size of equipment, sexual experience/ technique, overall attitude, the regularity in which they see you, session length (1, 2, 4 hours), tips received, or perhaps something else?  I know different providers may see things differently but I am curious to see if there are tends that will appear that could help us guys to become better clients and in return receive the absolute best service.

Guys, please include your comments as well as to why you believe you belong in the best client category and why.  It will be interesting to see the dichotomy of opinions from both sides of the equation.
